How to sign and send transfer transaction using waves-transaction JS library?

Question

Please help me understand https://testnodes.wavesnodes.com/api-docs/index.html I use this api and this library https://github.com/wavesplatform/waves-transactions I cannot send a transaction using the manual to the library or directly by POST request for api.

common mistakes:

• Error: State check failed. Reason: Script doesn’t exist and proof

• Error: State check failed. Reason: Transactions from non-scripted accounts must have exactly 1 proof

A POST request for url / addresses also gives an error. Provided API key is not correct. Here is my code:

const { transfer, broadcast } = require("@waves/waves-transactions");
const seed =
  "ride flee tenant tuna share buyer work west amateur review time kick";
const signedTranserTx = transfer(
  {
    amount: 1,
    recipient: "3NBVqYXrapgJP9atQccdBPAgJPwHDKkh6A8"
  },
  seed
);
const nodeUrl = "http://testnodes.wavesnodes.com";

broadcast(signedTranserTx , nodeUrl)
  .then(resp => console.log(resp))
  .catch(err => console.error(err));

[Update]

The above code working good. Just a quick update since I see the new testnet URI is below link:

https://nodes-testnet.wavesnodes.com

I mean I have replace from https://testnodes.wavesnodes.com to https://nodes-testnet.wavesnodes.com then it's working maybe because we created the account from the different place.

So this is the final code:

const { transfer, broadcast } = require("@waves/waves-transactions");
const seed =
"ride flee tenant tuna share buyer work west amateur review time kick";
const signedTranserTx = transfer(
  {
    amount: 100,
    recipient: "3N3pJ8xAnbaSBFdAbnaKe4yu4ZXbYkatMcN"
  },
  seed
);
const nodeUrl = "https://nodes-testnet.wavesnodes.com";
broadcast({ ...signedTranserTx, chainId: "T" }, nodeUrl)
  .then(resp => console.log(resp))
  .catch(err => console.error(err));
